Glass capillary tubes can be used as a support component for multiple facilities, as well as find a wide array of uses in optical fiber and telecommunication industries.

When it comes to the inner diameter’s precision, there is no comparable material available today that can achieve the same precision and consistency as the glass capillary tube in different lengths and production batches. Based on different designs and different applications, ZCQ is able to manufacture various kinds of glass capillary tubes and rods.
When classified according to precision, our glass capillary tubes or rods can be divided into high precision and medium precision. When classified according to shape, our glass capillary tubes or rods are divided into standard quartz capillary tubes, square-shape capillary tubes, cone-shape capillary tubes, D-shape tubes, special-shaped tubes (V-shape tubes, U-shape tubes), elliptic tubes, hexagon shape tubes, and custom special-shape tubes.
When classified according to the diameter of its hole, our tubes can be classified as round-hole tubes, dual-hole tubes, multi-hole tubes, square-hole tubes, elliptic-hole tubes, eccentric tubes, V-shape hole tubes, D-shape hole tubes, U-shape hole tube and custom special-shape hole tubes.
